he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.

This algorithm is to count the dark colored pixels in the input image. This can be used in goods sorting like rice, paddy etc... in paddy or rice or other goods or products to sort out the bad or defect one we can use this algorithm. I had done this for my Masters Degree as a small part and now i am releasing for you. rajesh.f, Kanayakumari district, India. contact me: rajesh1983jan10@yahoo.com
